Solution Overview
Problem
Existing golf club grips are difficult to securely attach to tapered shafts without professional assistance, and there is a need for a system that allows quick and easy replacement of grips on a variety of shafts.
Innovation Solution
A golf club grip system featuring a docking tube with projections and channels, an elongated handle with asymmetric channels, and a clamp assembly that allows for secure attachment and easy detachment without tools, accommodating varying shaft diameters through elastic deformation and interference fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional grip attachment methods are used, then secure attachment is achieved, but professional assistance and complex tools are required
Solution Approach 1:
The attachment system is divided into separate components: a docking tube with projections integrated into the shaft, and a grip with corresponding channels. This segmentation allows the grip to be attached and detached independently without affecting the shaft, enabling easy replacement while maintaining secure attachment through the interlocking projection-channel mechanism.
Solution Approach 2:
The docking tube serves as an intermediary component between the shaft and the grip. It provides a standardized interface with projections that engage with channels in the grip, mediating the connection between components with varying diameters and enabling tool-free attachment while maintaining structural integrity.
2Adaptability or versatility
If grips are designed for secure attachment to tapered shafts, then attachment security is improved, but adaptability to various shaft diameters decreases
Solution Approach 1:
The docking tube with its projection structure serves multiple functions: it provides a standardized attachment interface that accommodates various shaft diameters, maintains rotational alignment through the projection-channel engagement, and ensures secure attachment. This universal interface design allows the same grip design to be used across different shaft types while maintaining reliable attachment security.
Solution Approach 2:
The projection and channel features are designed with asymmetric geometries that provide directional engagement. The projections have specific shapes that fit into corresponding channels, creating a keyed connection that prevents rotation and ensures proper orientation. This asymmetric design maintains secure attachment while adapting to various shaft diameters through the elastic deformation capability of the materials.
3Productivity
If grips are made easily replaceable, then ease of operation is improved, but attachment security and stability may be compromised
Solution Approach 1:
The docking tube projections and grip channels are pre-configured in specific positions and orientations before assembly. This preliminary arrangement ensures that when the grip is attached, the projections automatically engage with the channels in the correct orientation, providing immediate rotational stability and secure attachment without requiring additional alignment steps or tools during the replacement process.
Solution Approach 2:
The intermediate sections of the docking tube and grip features incorporate curved surfaces and radii of curvature that facilitate smooth engagement and deformation during attachment. These curved geometries allow the elastic materials to deform smoothly during the pressing operation, ensuring secure attachment while maintaining the ability for quick removal by reversing the deformation force.

AI summary
A golf club grip may include a docking tube and an elongated handle. The docking tube may be configured to couple to a golf club shaft and may include a docking tube sidewall. The elongated handle may be detachably couplable to the docking tube. The elongated handle may include an elongated handle sidewall defining an axial opening configured to receive the docking tube. At least one of the docking tube sidewall and the elongated handle sidewall may include a projection and the other of the docking tube sidewall and the elongated handle sidewall may include a channel. The channel may be configured to receive the projection to prevent rotation of the elongated handle relative to the docking tube when the elongated handle is coupled to the docking tube.
